[gnulib] port fpurge.c, freadahead.c and freading.c + others for Haiku

[scottmc]

 http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/fpurge.c  http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/freadahead.c  http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/freading.c

These three trip up builds of m4, coreutils, findutils and probably many others.

Trying to debug this with testdir-stdioext from:  http://www.nabble.com/-PATCH--DragonFly-BSD-support-to17576603.html got make errors in: fbufmode.c, fpurge.c, freadahead.c, freading.c, freadptr.c, freadseek.c, fseterr.c, freadable.c, fwritable.c, fwriting.c and fseeko.c

Got pass each of those by addining in an defined HAIKU in the line with:

#if defined _IO_ferror_unlocked GNU_LIBRARY ==1 /* blah blah */ making it:

#if defined _IO_ferror_unlocked GNU_LIBRARY ==1 defined HAIKU /* blah

after changing those 11 files, make finishes without any further troubles. make check then fails 4 of 24 tests. Output attached.

I added a check for "defined __HAIKU__" on the "if defined _IO_ferror_unlocked" line in fpurge.c and it then allowed it to build, then tripped up on the next occurance of that same line in fflush.c. I did a grep on the coreutils tree and this is the result:

~> grep -nri 'IO_ferror_unlocked' coreutils-6.12
coreutils-6.12/gnulib-tests/test-fflush2.c:27:#if defined _IO_ferror_unlocked || defined __sferror /* GNU libc, BeOS; FreeBSD, NetBSD, OpenBSD, MacOS X, Cygwin */
coreutils-6.12/lib/fpurge.c:64:# if defined _IO_ferror_unlocked || (__GNU_LIBRARY__ == 1) || defined __HAIKU__ /* GNU libc, BeOS, Linux libc5 */
coreutils-6.12/lib/freadahead.c:27:#if defined _IO_ferror_unlocked || __GNU_LIBRARY__ == 1 /* GNU libc, BeOS, Linux libc5 */
coreutils-6.12/lib/freading.c:34:#if defined _IO_ferror_unlocked || __GNU_LIBRARY__ == 1 /* GNU libc, BeOS, Linux libc5 */
coreutils-6.12/lib/freadptr.c:32:#if defined _IO_ferror_unlocked || __GNU_LIBRARY__ == 1 /* GNU libc, BeOS, Linux libc5 */
coreutils-6.12/lib/freadseek.c:37:#if defined _IO_ferror_unlocked || __GNU_LIBRARY__ == 1 /* GNU libc, BeOS, Linux libc5 */
coreutils-6.12/lib/fseeko.c:47:#if defined _IO_ferror_unlocked || __GNU_LIBRARY__ == 1 /* GNU libc, BeOS, Linux libc5 */
coreutils-6.12/lib/fseterr.c:32:#if defined _IO_ferror_unlocked || __GNU_LIBRARY__ == 1 /* GNU libc, BeOS, Linux libc5 */
~> 

Seems those are the same files that are failing in the test program... Now should Haiku be setting _IO_ferror_unlocked or __GNU_LIBRARY__ or should i just add the defined __HAIKU__ to these files?

Add cvs to the list of packages blocked by this one.

fpurge() and freading() have been implemented in Haiku. freadahead() needs to be fixed in gnulib.

fixed recently in gnulib by Bruno Haible:  http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commit;h=a2c5f8d99ec52594aae96afeb29e0aeb7a841872
